Cheers Members !
i just bought a 1990 RRC with the 3,9 efi engine in it. had a p38 10 years ago - and loved it. saw the poor thing - always wanted a classic - and bought it.
Allthough the dealer said the engine would not turn over.
did a lot of research - the engine does turn over now - had a bad earth/ground connection.
It still wont start. when i turn the key, sometimes a lot of relays start clickering. the fuel pump relay, the aircon relay and also (sometimes) all the injectors of the rh side of the vehicle
2-4-6-8 clicker. even with the key only in pos. 1 8-()
every 5-10 times of turning the key - there is no clickering but the main relay - and the fuel pump power on (just got it new - old one was seized) actually as it should sound.
i have been looking into ground/earth issues - grindig off every bit of corrosion that i've found. the car had been resting for 15 Years.
did all electrical tests of the 24 step check. actually they all succeded - but the one aircon test (compressor was hoocked off.)
is it the ecu? i have no more clues where and what to look for. BTW i also have a weak spark. but it sometime did fire a little... (lil smoke out of the intake)
Fuel is running - pressure is ok (my first (standard) fuel hose bursted now have the high pressure version fitted to the test setup... Maybe some important info:
my fuel pump (at least i've heard so - doesnt shut off after 4 sec. it keeps running.
no more ideas on this. would love to see and feel it run.
on paralell im doing the "big anti rust program - lots of welding - footwells & wheelarches - but i think this is "normal" and ive seen worse on my 1999 Mercedes S500...
got to get the beauty back on the road...
thanks for every bit of help!
